HANGING BQOK-SHELVES.

SPECIFICATION forming part of Letters Patent No. 275,027, dated April 3,1883,

' Application filed October 16, l88i. (No model.)

To all whom it may concern:

Be it known that I, MAHLoN S. DRAKE, of Newark, in the county of Essexand State of New Jersey, have invented certain new andusefnllmprovements in Hanging Shelves; and 1 do hereby declare that thefollowing is a full, clear, and exact description thereof, referencebeing bad to the accompanying drawings, and to the letters of referencemarked thereon, which form part of this specification, in which Figure 1is a perspective view. Fig. 2 is a central vertical section. Fig. 3 is abottom plan view of the upper shelf.

This invention relates to special means for vertically adjusting theshelves of cases for holding books and for other purposes; and thenature of my invention consists in the combination of screw-threadedposts or stand ards and adjustable supporting-nuts for the purpose ofsupporting the shelves at any desired distance apart; and, also, innovel means for suspending the shelves, as will be fully understood fromthe following description, when taken in couucction witn the annexeddrawings.

The letters A A designate a number of shelves which are designed forsupporting books or any other articles desired, and B B B B are fourscrew-threaded posts which pass freely through the corners of theshelves, so that the latter can be readily raised or lowered. The topshelf is supported upon end transverse bars, 0 0, into or through theends of which the posts are screwed, as shown in the drawings. eachcross-bar G is an eye-piece, a, which passes through the top shelf, andhas hooked to it a suspension-rod, D, having an eye on its free end. Thesuspension-rods D D have hooks on their free ends for attachment toscrew-eyes fixed into a wall, and it will be seen that these rods can beadjusted toward or from each other at different angles, according to thedistance apart of the said screw-eyes. As above stated, the posts B arescrew-thread ed, and on the posts flanged nuts E are applied,

At the middle of the length'of.

having threads of considerable pitch, so that they can be moved up anddown quickly. The flanged nuts are preferably of cast metal, althoughthey may be made ofhard wood. Each corner of every shelf below thetopmost shelf has a nut, E, beneath it. These nuts afford supports forthe shelves and allow the shelves to be adjusted up and down on theposts and supported by the nuts at whatever distance apart it may bedesired to adjust them.

Instead of the eye-pieces a a, or in addition to these eye-pieces,eye-nuts may be screwed on the upper ends of the rods B, which wouldserve as clamps for the top shelf, and also as means for attachingsuspension-cords to the posts.

It will be seen that the several parts composing the improved case canbe detached from each other and closely packed for transportation orstorage.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

1. A series of adjustable shelves, A, in combination with screw-threadedposts B and the adjustable supporting-nuts E for the shelves,substantially as described.

2. The combination of adjustable shelves A, the screw-threaded posts B,the supportingnuts E for the shelves, the top stationary shelf, and thetransverse supporting-bars G therefor, substantially as described.

3. The combination of adjustable shelves,

screw-threaded posts, adjusting supporting- MAHLON S. DRAKE.
